This invention relates to improvements in dough rolling machines, especially for roll` ing pie crusts and the like. In rolling pie` crests a ball or lump of dough Acontaining about the right amount of material for the desired size of crust, is fed by hand through a wide pass between a pair `of rollers toy flatten the dough, the length ofthe flattened dough being nearly equal to the diameter of 1o the finished pie crust. The flattened piece` of dough is then fed sidewise through a narrow pass wherethe doughr is furtherlfiatf tened into a thin circular sheet.

Since the `number of crusts produced by l5 the machine depends largely upon thespeed to which the manual feeding operations can be performed, especially in handling the dough at the intermediate stage, dough rollingl machines have been built in the past with two pairs of rollers, arranged one above the other, and at right angles to each Other.

When the dough was rolled out of the first pass between the upper rollers, it was received on an apron in front of the second pair of rollers, with the result that the Operator was only required to flip the dough sidewise into the narrow pass to iinishthe crust. Such machines were quite expensive to build, and required considerable space. Accordingly cheaper machines were designed which had a single main roller with two shorter rollers arranged side by side above the main roller, to form, in conjunction with the main roller, a wide and a nar- 'd row pass. The operator was then required to turn the dough and lift it up over the rollers to feed it through the second pass. 1t is Obvious that Such an operation was rather difficult and fatiguing and that a high rate of production could not be obtained.

ln this invention a main roller is provided wi th a small roller above one end for forming the wide pass, and another roller below the other end of the main roller for forming the narrow pass, so that the operator is only7 required to pull and turn the dough at the intermediate feeding operation.

An illustrative embodiment of this inven- .between "the end frames.

`tion" of the shaft 15 is mounted a short roller tion is shown in the accompanying drawings, in which:

Fig. 1 is a front elevation of the machine, looking from the operators position.

Fig. 3 is a plan view of the machine.

Fi 4 is a side elevation of the front portion of the machine. f

Fig. 5 is a section taken on the line 5*5 of Fig. 3. i i i In the construction the end frames 6 and? each consisty of the bearing members 8 and 9Whichare mounted on posts 10 and 11 Which are secured in the ends ofthe rectangular base plateA 12. `The members 8 and 9 are slidable, one above the shown in the drawing, f

otheron the posts l() and 11, and are seset screws 13.

mounted at their ends in the bearing members 8, and shaftl `is rotatably mounted in the lower bearing members 9. The shaft 14 is fixed inposition, and the shafts 15 and ,the l adjustment being accomplished by means of eccentric bushings 17, `which are The shafts 14 and 15 are rotatably s f 16 are adjustable in relationto the shaftr 14, f

The bushings 17 are provided with handlesy f 18 formanipulajtion, and are locked in the desired position byany suitable means,`such as the setscrews 19. y v f The main roller 20. iskeyed on the shaft 141, and extends entirely across the machine On the rear por- 21 which cooperates :with the rear portion of the main` roller 20 to form the wide pass A, as is more clearly shownin Fig. 5;y and the 'roller' 22, for forming the narrowgor finishing pass B, is mounted below the main ,roller 20, `on".the shaft 16. Preferably the shafts L15 and '16 are `each Offset atianl angle of about 25 degrees to the right of the main roller shaft` 14, sothat the dough eanfbe more` easily fed between the rollers.v

The driving arrangement is as follows: on the rear end of the shaft 16, which projects beyond the frame 7, is keyed a large gear wheel 23 which is driven by the pinion 24 which is mounted on the shaft 25 of the motor 2G, the motor being mounted on the base plate 12. Motion is communicated from the shaft 16 to the shaft 14 by the equal sized gears 27 and 28 which are keyed respectively to the shafts 16 and 14, vand the motion is communicated from the shaft 14 to shaft 15 by the equal sized gears 3() and 3,1 which are keyed to the shafts 14 and 15 respectively. By this arrangement the rollers are driven at the sam-e speed, the dough is rolled to the right through the pass A, andv back to the left through the pass B.

At the. left of the roller 21 is provided a hopper 32 .tor receiving the ball of'r dough, and guiding it through the pass A. The hopper 32 may be hung on the shafts 14 and 15 as shown, or tixedly mounted in any suitable manner. At the right side of the machine is provided a shelf 33 which,'in the construction shown, is removably mounted in suitable brackets34 which are formed integrally with the lower frame bearing' members 9. The scraper blade 35 is rigidly secured at one end tothe sheltl 33,A so that the Vopposite end bears on the surface of the roller 20,- to free the dough from the roller and to guide the dough on to the sheltl At the left side of the machine, the dough is rolled out through the narrow pass onto an apron 36, which may be suitably supported so that the upper end serves for scraping `the dough 'from the' surface of the lower roller 22. f A In using the machine, the operator throws the ball of dough into the hopper 32 which guides the dough through the wide pass A, the dough being rolled out to the right side of the machine onto the shelf 33, the operator then pulls the dough towards the front ot' .the machine, turning. it and feeding it to the left through the narrow pass B, through which it is rolled out onto the apron 36 in inished form. In cleaning the machine, the hopper, shelf, and apron may be removed leaving the rollers exposed.

Obviously the construction of the machine isvery simple, and the machine can be produced at a low Cost so that it is available to a Vgreat number' of users. The feeding operations are very simple, and can be periformed at a high rate ot' speed, The necessary adjustments can be easily accomplished, and the part-s can be easily removed ior cleaning. Vhile but one illustrative embodiment of this invention has been shown and described, many alterations and omissions may be had without departing from the spirit of the invention, as deiined in the 'following' claims.

l claim:

1. In a. dough rolling machine, a main roller, a roller arranged above one end of the main roller to form a wide pass for iiattening the ball of dough, and a roller arranged below the other end of the main roller to forni a narrow pass for rolling the 'flattened dough from the wide pass into a thin. circular sheet.

2. in a doughV rolling machine a main roller, a roller arranged above one end of the main roller to form a wide pass, a roller arranged below the other end or(l the main roller to form a narrow pass, a hopper mounted'at one side of the main roller for guiding thc dough into the wide pass, and ay shelf at the opposite side ofthe main roller for receiving the dough from the wide pass and for use in transferring the dough into the narrow pass; f

3. A dough forming machine comprising a frame, a main rroller journaledV in said iframe, a roller arranged above one portion of said main roll-er in laterally offset relation thereto i'or effecting one operation on the dough passed therebetween, a roller arranged below a diiierent portion of said main roller in laterally oiiiset relation thereto for eii'ecting another operation on said dough, a shelf for receiving said dough atter said iirst operation and for facilitating placement thereof for the second operation, and an inclined apron engaging said last-mentioned roller for removing and conveying the dough therefrom.
